Subject: Re: Getting complicated
The starting assumption is that you *want* a re-entry, so (4) is better than (2), as it is more likely to get you the stock. The outcomes are otherwise quite similar.
And if you don't get the stock, then (3) is far preferable to (1).

Yes, so you can pick a strike & premium that yields the probability of owning the stock that you find acceptable (and net cost).

Or write puts at multiple different strike & premium combinations. The cheaper the price, the more you buy.
